  • Method and apparatus for wireless communications for base station controllers
    Patent number: 6175737
    Abstract: A cellular communication system having a plurality of wireless in-band channels and having a plurality of cells with a plurality of mobile stations in each cell where a base station (BTS) is the interface between mobile stations and a base station controller (BSC). The base station controller monitors and controls one or more base stations. A wireless trunk is established between the base station and the base station controller using selected ones of the allocated channels otherwise available for mobile station communications.

  • Complex quotient nuclear magnetic resonance imaging
    Patent number: 4649346
    Abstract: In an NMR imaging system, an image plane is scanned and NMR signals are collected over a plurality of image lines. The experiment is repeated, with the timing of the excitation pulses changed. Images are formed by performing Fourier transformations of the signal values. A ratio image is then formed by performing a complex division of the two images on a pixel by pixel basis. The ratio values cancel phase error effects in the image data and the use of complex numbers maintains the proper pixel polarity.
